User Testing

It’s important to do both automated and manual testing. Automated testing checks the website structure against success criteria in the WCAG 2.0+ guidelines, while manual testing will ensure the user experience is actually accessible for people with disabilities.

For automated testing of HTML and the website’s coded structure, you can use:

• WAVE Tool (WebAIM)
• A-Checker (IDRC)
• Checklist for WCAG Compliance (A11y Project)

Manual testing resources and samples:

• The 1-Page Usability Test Plan – David Travis
• User Testing Protocol – Fluid
• Usability Test Plan Template – Usability.gov
